Do bullets go faster than the speed of sound?
When bullets fly through the air, they do so at amazing speeds. The fastest bullets travel more than 2,600 feet per second. That’s equivalent to over 1,800 miles per hour. To put that in perspective, it’s amazing to realize that bullets travel over twice the speed of sound!
Why does a bullet slow down?
When fired horizontally, bullets tend to slow down rapidly due to air drag, so that a rifle bullet may be down to half of its initial speed by the time it gets to 500 meters (1,640.42 feet), Walker says. “If you choose to shoot it up, it will slow down faster because of gravity, not a whole lot.”
Will a bullet fired horizontally take longer to fall to the ground than a bullet simply dropped from the same height?
There you have it. The y-component of air resistance for the fired bullet still depends on the fired speed of the bullet (since it is proportional to v2). A fired bullet (with air resistance) does not hit the ground at the same time as a dropped bullet.
Does a fired bullet break the sound barrier?
No, it doesn’t sound like a jet breaking the sound barrier. For perspective, the speed of sound is roughly 1,135 feet per second (fps) with some variation for temperature, humidity, and altitude. Many handgun loads propel a bullet faster than sound. All rifles loads do.
What determines the speed of a bullet?
Given the above: Bullet velocity is primarily determined by bullet mass, bore cross-section, and barrel length. Holding cross-section and length constant, a lighter bullet has a higher muzzle velocity (i.e., the velocity at the moment it leaves the barrel and can no longer be accelerated by the propellant).
How does friction affect a bullet?
The friction actually takes away from the kinetic energy of the bullet, making it into heat energy. A decrease in kinetic energy means the bullet is being slowed down by this friction.
What would hit the ground first a bullet fired from a gun or a bullet dropped Why?
In reality, we have air resistance to deal with. Air resistance slows down a speeding bullet, and so you’d think that it would hold the fired bullet back, so that the dropped bullet would hit the ground first. But wait! The dropped bullet is also moving through the air, and it experiences air resistance as well.
Why does a gun recoil when bullet is fired?
When a bullet is fired from a gun, the gun exerts a force on the bullet in the forward direction. This is force is called as the action force. The bullet also exerts an equal and opposite force on the gun in the backward direction. Therefore a gun recoils when a bullet is fired from it.
Do bullets fall down the same speed as they go up?
A: The answer to your question is both yes and no. In the non-existant world where only gravity matters, yes, the bullet would come back down at exactly the same speed as it went up. This is because gravity works to slow things down AND to speed things up.
How does air resistance affect the speed of a bullet?
The bullet is traveling very rapidly, mostly horizontally, but with a small downwards component. Air resistance provides a force that increases nonlinearly with speed, and so the vertical component of the air resistance force will be greater for the horizontally shot bullet than for the dropped bullet.
Why do bullets hit high when shooting at angles?
Len Backus of Long Range Hunting Online Magazine says, “There is a physical ballistic problem encountered when shooting at angles that causes the bullet’s point of impact to hit high.” The solution? Aim lower.
Should you aim higher or lower when shooting a rifle?
The trajectory of a downhill shot is the same as that of an uphill shot, says Russell. The conclusion: Aim lower. The following websites address aiming points for rifles: William McDonald of Exterior Ballistics.com stated that “in an angled situation, a gun will always shoot high compared to shooting on a level trajectory.”
